SAFETY UA1? .FOR GASOLINE TANKS.

Application filed April 17, 1924. Serial No. 707,091.

To all whom t may concern.'

Be it known that I, JOHN A. MARTE, a citizen ofthe United States, residing atv Santa Ana, in the county of Orange and State of California, have invented new and useful ln'iprovements in Safety Caps for Gasoline Tanks, of which the following isa specification.

This invention relates to a safety cap for containers and is especially adapted as a cap for gaso-line tanks in automobiles.

An object of this invention is the provision of a safety cap for` gasoline tanks, or the like, said cap -comprislng means for preventing its loss.

Another object lof this invention 1s the provision of a safety cap for gasoline tanks, said cap comprising means by which gasoline may be conveniently entered in a tank.

With the foregoing objects in view, together with such other objects and advan tages as may subsequently appear, this 1nvention consists in the construction and arrangement of parts hereinafter described and claimed' and illustrated in the accompanying drawings, in which:

Figure 1 is a vertical section of the cap, showing its application to a gasoline tank, which is shown in part,

l"ig.'2 is a. View similar to Fig..1, but showing the cap in raised position, and receiving a filling nozzle from which gasoline enters the gasoline tank, and

Fig. 3 is a cross section taken on the line 3 3 of Fig. 1.

Referring to the drawings for a more detailed description thereof, the numeral 5 indicates a gasoline tank .having an aperture 6 through which the tank is adapted t'o be filled. The tank also comprisesa nipple 7 adjacent the aperture 6, and the nipple 7 is outwardly threaded at its upper end portion to receive' female threads formed 1n a cap portion 8, which holds on its lower face a washer 9. The cap portion 8 has a lateral air hole 10 fand a vertlcal aperture 11. The aperture 11 is made square on its upper portion 12. The aperture 11 is adapted to receive a bolt 13, which is made square at its upper end portion to engage the square portion of the aperture 11.

The bolt 13 comprises a head 14 which rests on the upper end of the cap portion 8. The bolt 13 1s threaded at its lower end. A cylindrical tube 15 is adapted to-contaet at its upper end with the under face of a.

cap portion 8 and comprises a-transversel member 16 provided with a central aperture througliwhich the bolt 13 passes, and the lower end of which 'the bolt 13 threadedly engages. A nut 17 isscrewed on the bottom of the bolt 13. The member 16 has a vertical air holev 18. The tube 15 is provided with a lateral aperture 19 adapted to re-v ceive a filling nozzle 20, as shown in Fig. 2, when the cap portion 8 is removed from the nipple 7 and the tube 15 is raised. The lower portion of the tube 15 is provided with a plurality of springs 21,'the lower endsl of which are secured in any suitable manner to the sidesl of the tube 15. The springs 21 comprise a portion 21 disposed at an angle to the Vaxis of the 7tube 15 and a horizontal portion 21h which projects into the` tube 15. j .Before applying a' cap in its entirety to 'the tank 5,? the parts of the cap are 'as-v sembled by placing the washer 9 on the under face of the c'ap portion 8, placing the upper end of the tube 15 in contact with the. under face of the cap portion 8 and inserting the bolt 13 through the aperture 11 and threading it through the lower part of the central aperture of the transverse member 16. The nut 17 is then screwed on to the bolt 13. In applying the cap to the portion of the tube 15 enters the tank.`

lVhen the cap .is raised for the insertion of the filling nozzle 20 into the aperture 19, the horizontal portions 21b of the springs v21 come into4 contact with the upper.' portion of the tank, as shown in Fig. 2 and thereby prevent the entire removal, an conuent possible loss, of the cap. .e

y safety cap forms a simple and elficient device to prevent the splashing of vgasoline in pouring it into a tank from a straight fillin nozzle 20 or the spout of a filling can. T erefore a Simple modification of my invention is to discard the springs 21 and substitute for the cap anyjdevice which will prevent the tube 15 from drop' ing into the tank when itis placed over a filling nozzle. p

Thls invention has been described, but modicationsthereofmay be devised without departin fromthe spirit thereof, and it is to be. un erstood that such modifications come within the scope of this invention.

What is claimed is: l. A safety cap for gasoline tanks, comprising in combination a tank having an externally screw threaded nipple, a cap 5 fitting thereon having an upward extension with a vert-ical aperture therethrough, a cylindrical tube having a transverse member at its upper end and a lateral aperture for a filling nozzle, a bolt extendiing l0 through the `vertical aperture in the cap and bolted. to the transverse member of the tube and angular spring fingers attached to i the lower end` ofthe tube'havng horizontal parts engaging in the tube to allow insertion, but preventing removal of the tube I5 from the nipple.

:2. A safety cap for gasoline tanks as claimed in claim '1, having in addition an air aperture through the transverse member in the tube and a lateral air hole through the 20 upper portion of the extension of the cap.

In testimony whereof I have signed my name to this specification.
